Slither.io but where you can input whole body gestures,
with
a camera or other sensor. I find myself player slither.io for
social contact. Did I just say that?

This slither will be totally configuarable so you can use and
modify your own controller and your presence in the slither
world,
the standard being that all players on the board start
roughly equal in size and elongate as they eat food. use
kinnect to slither in 3D. the food should have gravity also
and be usable as stuff to throw at other players.

He wants to multiplayer wii. I do like the idea of using the whole body as a mouse like controller - I have to think that has been done since it seems like folks have been using camera inputs for about a decade.

It is interesting, the social interactions possible with these pared down soundless, textless games like slither or agario. It would make a fine PhD thesis I think.
